Advanced Mobile Gestures and Interactions in Appium For Realistic Test Scenarios

Introduction

As mobile test automation continues to gain traction, teams are realizing the need to move beyond functional test scripts and replicate actual user behaviors more realistically. This is crucial for comprehensive validation before releasing apps into the hands of customers.

 

Going beyond tapping buttons, Appium unlocks advanced mobile gestures like swiping, dragging, pinch-zooming, rotating and more. When combined together, these multi-touch interactions create practical test scenarios mirroring real-world usage patterns. For instance, verification flows can include searches, exploration of features, form submissions and payments.

 

This article explores how automation engineers can leverage Appium’s mobile gestures toolbox to craft end-to-end test suites. We look at practical implementation patterns and tips to handle native, hybrid and mobile web apps.

Basic Mobile Interactions with Appium

Appium allows automating some of the most fundamental user interactions on mobile devices like taps, swipes, scrolls and clicks. These basic building blocks open up possibilities for testing a wide variety of mobile apps spanning different genres like shopping, travel, food, ride-sharing and more.

 

At the core, Appium relies on the WebDriver protocol to drive native, hybrid or mobile web apps similar to how an actual user would interact. Actions like tapping buttons, entering text in forms, navigating between screens using swipes and scrolling long lists are all basic interactions supported out of the box.

 

On the native app side, Appium leverages vendor-specific frameworks like UIAutomation (iOS) and UIAutomator (Android) that provide APIs for hooking into UI elements and simulating user actions. For mobile web, Appium can switch context to web views and leverage Selenium to interact with web elements.

Implementing basic interactions in Appium tests

Here are some examples of code snippets to perform basic UI interactions:

// Tap on a button

WebElement loginBtn = driver.findElementByXPath("//*[@text='LOGIN']");

loginBtn.click();

 

// Enter text in a textbox  

WebElement username = driver.findElementById("username");

username.sendKeys("john.doe@email.com");

 

// Swipe screens

driver.swipe(100, 1500, 100, 500, 2500);

 

// Scroll in a long list

driver.findElementByAndroidUIAutomator(

   "new UiScrollable(new UiSelector()).scrollIntoView(text(\"Desired item\"));");

Limitations of basic interactions for testing complex scenarios

While taps, swipes and scroll provide a starting point for test automation - they are not sufficient for building robust, extensive test suites for modern feature-rich mobile apps.

 

Testing complex real-world scenarios require simulating advanced touch actions like pinch-zoom, drag-drop across screens, holding long tap to reveal hidden menus and detecting shake gestures.

 

Also basic interactions fall short of testing device capabilities like rotation, split screen, accelerometer data or hardware back button. Rigorous mobile testing needs to account for network transitions, GPS location mocking, native notifications and external hardware.

 

So while Appium provides a range of basic user actions - teams need complementary solutions like cross-platform cloud device labs, a device farm,  mobile DevOps integrations and unified test asset management to overcome limitations and achieve continuous quality.

Advanced Gestures in Appium

Advanced touch actions and gestures are important for comprehensive mobile test automation with Appium. They allow simulating complex real-world user behaviors going beyond just tapping buttons and typing text.

Some of the commonly used advanced mobile interactions include:

• Multi-finger gestures

Appium supports multi-touch gestures like pinch/zoom, scroll, rotate and swipe using two or more fingers. These come handy to test various functionality like zooming maps, scrolling feeds, rotating images etc.

 

For example, pinch zoom can be performed on a map element as:

// Pinch zoom on map

WebElement map = driver.findElementByXPath("//*[@resource-id='com.app.map']");

TouchAction zoomMap = new TouchAction(driver);

 

// Zoom in map

zoomMap.press(map, 100, 200)

    .moveTo(map, 50, 100)

    .release()

    .perform();

 

// Zoom out map

zoomMap.press(map, 50, 100)

    .moveTo(map, 150, 300)

    .release()

    .perform();  

Here we are pressing the map element at (100, 200) coordinates and moving the second finger inward towards (50, 100) to pinch and zoom in. Similarly, panning out the fingers in opposite direction zooms out by pressing at (50, 100) and moving outwards to (150, 300).

• Swipe across screen

Swiping the mobile screen is used extensively for navigating between screens and menus. Appium provides methods to swipe the screen in four directions: UP, DOWN, LEFT and RIGHT.

For instance, horizontal right swipe can be done as:  

// Swipe screen from left to right

driver.swipe(100, 1000, 700, 1000, 2000);

 

This will swipe the mobile screen from x-position 100 to 700 on y-axis 1000 over 2 seconds. The speed and distance can be parameterized for longer or quicker swipes.

• Long press actions

Long press gesture helps to mimic holding tap on an element for a longer duration. This brings hidden menus and options related to the element, simulating complex real-world interactions.

Example code:

// Long press on an image to activate share menu

WebElement image = driver.findElementById("img156");

new TouchAction(driver)

  .longPress(LongPressOptions()

 .withElement(element(image))

 .withDuration(ofMillis(2000)))

  .release()

  .perform();

Here we are long pressing the image for 2 seconds to bring the share context menu.

• Device rotation

We can change device orientation between landscape and portrait modes:

// Rotate to landscape mode

driver.rotate(ScreenOrientation.LANDSCAPE);

 

// Rotate to portrait mode

driver.rotate(ScreenOrientation.PORTRAIT);

This helps to seamlessly test orientation-specific UI changes.

 

The advanced touch actions and mobile-specific interactions enable creating incredibly realistic test automation for different mobile gestures, menus and behaviors - taking Appium automated testing to the next level!

Handling Complex Interactions

Here is a detailed guide on handling complex interactions in automated testing:

A. Dealing with scenarios requiring multiple gestures and interactions

As mobile apps become more immersive with gestures like swipe, drag, pinch, zoom, long tap and device motions - testing needs to keep pace with simulating increasingly complex user flows.

Let's take an ecommerce app for example. A user might:

• Swipe through multiple products
• Tap a product and pivot images to view in landscape mode
• Pinch-zoom into finer details of the product  
• Long press on image to save it
• Shake device to undo an action
• Click heart icon to favorite and add to wishlist
•  Rotate device to view cart in landscape orientation

 

We can see flows require orchestrating various gestures, device capabilities and network requests in a sequence reflecting actual usage - instead of just tapping buttons. Some effective strategies for handling such complex interactions include:

• Custom interaction methods

This method wraps complex action sequences behind simple descriptive methods. Instead of repeating code, have reusable steps that translate to business functions:

// Method to favorite a product

public void favoriteProduct() {

//Swipe to product

  swipeScreen(START_X, END_X)

//Tap product and view images

  tapProduct()

//Long press image to save

  longPressImageToSave()

//Click heart icon

  clickHeartIcon()

 }

• Chaining patterns and parallel execution

Appium facilitates chaining actions using TouchAction and MultiTouchAction classes. This helps encode sequenced flows easily:

TouchAction action = new TouchAction(driver);

action.tap(x1,y1))

    .longPress(x2,y2)

    .perform();

We can also execute gestures in parallel to reduce test time.

• Page object modeling

Page objects abstract UI screens into logical blocks while hiding underlying complexities:

class LoginPage() {

  LoginPage(driver) {

  this.driver = driver;

  }  

  login() {

 driver.sendKeys(username, pwd)

 driver.tap(loginBtn)

  }

}

B. Strategies for handling complex interactions efficiently

Some effective strategies include:

• Break down long flows into reusable steps or user journey modules that can snap together.
• Offload environment handling into drivers - so tests only focus on customer journey.
• Cross-platform normalization layers help de-couple tests from underlying mobile platforms.
• Well-defined page objects, utility classes encapsulate complex action Implementations.  
• Generating actionable test failure data, screenshots and logs help debug failures faster.
• Visual validations for UI elements, system notifications, pop-up windows.
• Integrating chaos testing principles to induce random environmental conditions.
• Monitoring resource utilization for stability under complex flows.
• Architecting for distribution helps execute complex flows faster.
• Adopting Behavior Driven Development promotes living business documentation.

By leveraging some of these strategies, mobile test automation teams can sustainably scale up automation coverage to handle the complexity of mobile applications and customer usage patterns.
